The ACE inhibitor, captopril, lowers blood pressure and helps prevent strokes, heart attacks, and kidney problems.
Hydrochlorothiazide is a “water pill” (diuretic) that increases the amount of urine you make, causing your body to get rid of extra salt and water. This medication may also be used to treat congestive heart failure.
How to use captopril-hydrochlorothiazide
Take this medication by mouth on an empty stomach one hour before a meal, usually once daily or as directed by your doctor. It is best to avoid taking this medication within 4 hours of your bedtime to avoid having to get up to urinate. Consult your doctor or pharmacist if you have questions about your dosing schedule.
Drink plenty of fluids to prevent losing too much body water (dehydration). If you are on restricted fluid intake, consult your doctor for further instructions.
If you are also taking cholestyramine or colestipol, take captopril/hydrochlorothiazide at least 4 hours before or at least 4 to 6 hours after either of those drugs.
The dosage is based on your medical condition and response to therapy. The manufacturer recommends that daily doses should not be more than 150 milligrams of captopril and 50 milligrams of hydrochlorothiazide.
Use this medication regularly in order to get the most benefit from it. To help you remember, take it at the same time each day. Do not skip doses or stop taking this medication unless directed by your doctor. It is important to continue taking this medication even if you feel well. Most people with high blood pressure do not feel sick. It may take up to 6-8 weeks before the full benefit of this drug takes effect.
Inform your doctor if your condition worsens (e.g., your routine blood pressure readings increase).
